Payment schedule runs can complete successfully even if some installments attached to the schedule fail. This ensure isolated issues do not block the entire collection process.
If you see a payment schedule with the status Success with Failure, one or more installments could not be collected.
Individual installments can run into errors in an otherwise successful schedule run. The best place to start is data quality. Use the Data Quality component on the installment to check and fix obvious data issues.
The failed installment may have gone through the collection process, but an issue on the payer’s end can lead to a failure. This is when you should check the Last Status Reason field on the installment. This will tell you if the failed installment is due, for example, to an expired credit card.
Once you have resolved the issues with the installment, you can set the installment status back to a pre-collection status (e.g. New or Pending recollection). This allows the installment to be picked up by the next payment schedule.
